Specification of Letters Patent.

Patented Feb. 8, 1916.

T 0 all whom it may, concern ;Be it known that I, HIRAM Sronnnprincipalob ect of the invention is to pro-- ,vide a new and improved type ofrail anchor which will be simple in construction, light in weight,inexpensive to manufacture and strong, and which will take a firm andreliable hold on the rail which will not be disturbed by vibration,difference in contraction and expansion as between the parts of thedevice and therail, due to temperature changes, or to other causestending to impair the gripping or holding ower which is essential to theetficiency o a device of A furthera'nd specific object of the inventionis toiprovide a novel form of rail anchor utilizing springpressure foreffectjingand maintaining an intimate clamp of the device on the rail.

A further object is to provide a device in v provide a device, the gripof which on the rail will not be affected bv a retrograde.

movement of the rail,,that is, a movement contrary to the normal creep.

The invention is illustrated, in certain preferred embodiments, in theaccompanying-drawings whe rcin igure 1 illustrates, in elevation, ar1111 anchor, constructed inaccordancc with the invention, applied to arail which is shown in cross section; Fig. 2, a plan view of the partsshown in Fig. 1; Fig. 3, a sectional view on line 3-3 of Fig. 2; Fig. 4,a sectional view on line 44 of Fig. 1; Fig. 5, a view, in perspective,of the spring wedge constituting one of the elements of the device shownin the preceding figures, and Figs. 6, 7 and 8, views correspondingrespectively to Figs. 1, 2.and 5 illustrating a modified form of theinvention.

Like characters of reference designate like parts in the several figuresof the drawings.

- In the drawings, 10 designates a railroad rail and 11 one of the crossties on which the railis supported.

Referring rst to Figs. 1 to 5 inclusive, the rail anchor herein shownmade up 'of two elements, a yoke 12 which extends around the base flangeof the rail, being formed at opposite endswith jaws 13 and 14, and awedge member 15 which intervenes between the ]aw 14 of the yoke and therail 10. ()ne of these elements, preferably the yoke 12, is formed witha tie abutting flange 16, or other suitable means, for giving the devicea stationary position on the road-bed as against a forward creepingtendency of the ral The element 15 has preferably a certain amount ofelasticity. In'this particular enibcdiincnt of theinvention itconsists'of a steel plate which is bowed-up from the base flange of therail, Fig, 5 being a view of the under side of the eleliient. It ispreferably formed with an upturned rim 17 by means of which it may bedriven between the base flange of the rail and the jaw 14. The elementis in the form of a wedge, being wider at its rear edge than at itsforward edge, and

is prefcrablv formedwith a depending flange 18 which overhangs,bntnvithout touching, the vertical edge of thebase of the rail; Theflange 18 is by preference wedge-shaped as shown and formed with aninturned tooth 1 l The device, constructed as above described,-

of the hold of the device on the rail under.-

varying conditions particularly as against thetendency of the device tobecome loose on the rail due to unequal expansion and "contraction ofthe rail and the anchor parts comprises an element which 18 wedged b andas against the loosening tendency due twee'n the other element and theupstanding to vibration. The tooth -19 prevents any web of the rail. Iretrograde movement of the wedge. If de- 4. A rail anchor comprising twomil sired,the tooth may be set into the rail, after gri pingelementskone of which is formed the anchor has been adjusted to itsoperative wit means for giving the device a fixed position, byhammering. It will be obposition in the road' 'bed as against the tendserved that the tie abutting plate 1Q holds ency of the rail tocreep,'oneof which comthe endof the yoke having the jaw 13 out prises as ring member whiehbears upon of con'tact with the tie 11 so that aforward the top the base flange of the rail, and

- creep rocks the anchor on the rail so as to the other a yoke whichembraces saids'pring increase all of -'the holding stresses.

In Figs. 6 .to 8 inclusive, I have shown a rail anchor similar to thatshown in the preceding figures except :for a modification in the :formof the wedging member. The device consists of -'yoke 20. having a tieabutting flange 21 and-jaws 22'and' this part of the device'being'substantially the same as the corresponding element in the Iother-anchor. The other member consists of. a bowed elastic'plate 24 ofless width than the. base flange which it, engages, p formed onits outeredge witha depending" wedge-shaped flange 25. ;;When the member 241sdriven in jbetweii the jaw 23 and the base of the rail it-is compressedor flattened, .'as in "theother construction, but does not bear againstthe upstanding web of the'rail.

39 .The wed ing action is produced bythe contour of t e flangeor rib 25,The latter'may be provided at its rear end with atootl 2fia While I havedescribed m flinventi'on as embodied in certain-preferre constructionsmodifications/might be made without departure from-theprlneiples. of'theinvention. Therefore-I. do not wish to be:understood as limiting theinvention to'the particular constructions, arrangements and de- 0 "icesshownand described except so far as these-limitations are specificallyset forth """in certain of the claims herein.
